Description

{AUTOMATIC BASEBALL LAUNCHER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic launch device for a baseball ball, and more particularly, to an automatic launch device for a baseball ball, which is convenient to carry and move, and can be used for training of athletes by automatically launching the baseball at a desired speed.

In general, in ball games such as baseball, athletes, including coaches, coaches, and athletes, either manually throw a ball into the ball or strike it with a bat to provide athletes the ability to attack and defend, I am training.

To this end, an assistant who supplies the baseball is essential, and such an assistant must supply the baseball ball precisely to the position necessary for improvement of various personal skills of the athlete.

However, it is inconvenient for an assistant to be repeatedly throwing a baseball ball in a certain direction and speed with a hand in the direction of a batter, or hitting it with a bat and supplying it to the athletes while the assistant is handling a lot of players, And there is a problem in that it is difficult to expect a continuous training effect on the players because accuracy is low.

In order to solve such a problem, various kinds of launch devices have been developed which can automatically fire baseball balls to improve individual skills of athletes. The launch devices using a spring machine, the launch device employing a rotary wheel, And a launch device using a blow.

For example, US Pat. No. 3,757,759 to J. G. Hawsworth, US Pat. No. 3,757,759, discloses a automatic pitching type ball throwing apparatus, and US Pat. No. 4,524,749 to Paul S. Gibbogornis discloses a spring type ball pitching machine.

In addition, as a launching device using a blow, Korean Utility Model Registration No. 20-0369723 discloses a blowing unit including a blowing unit composed of a blowing unit connected to a driving motor and a blowing unit for receiving a blowing air supplied through a blowing supply network, And a control panel for controlling the striking portion, the supplying portion, and the angle adjusting motor.

However, among the above-described conventional techniques, there is a problem that the launch device using the spring has low durability and difficulty in controlling the direction and the speed, and the launch device using the blow has a separate configuration The structure is complicated, the operation is inconvenient, and the ball is not provided with a structure for stably positioning the ball in the guide when the ball exits the supply chain and enters the ball rest, There is a problem.

On the other hand, as a launch device employing a conventional rotary wheel, a common wheel ball propulsion device of Norman Esserra, US Pat. No. 3,815,567, is disclosed.

However, the above-described conventional technique requires extensive adjustment and reorganization of the launching apparatus for switching to other balls or launch speeds and angles, and it is difficult to precisely control the balloon, resulting in inefficient training, Since the launching is unstable, it can be easily moved by the vibration when the ball is launched, the ball is inconvenient for movement and storage due to its large size, and the launching rod is installed upwards in front of the driving wheel, There is a problem in that the training efficiency is inferior because it is difficult to secure visibility and coping is difficult.

In particular, in baseball games, there is a difference between batting and defense techniques depending on whether the batter or pitcher is right-handed or left-handed. Therefore, all of them can be trained and the training efficiency is increased by transmitting baseball balls at various angles and speeds , The demand for an automatic launch device for a baseball ball which is convenient to carry and move by having a compact volume is increasing.

The present invention has been devised to solve all the problems described above, and it is an object of the present invention to reduce the fatigue of an assistant by automatically launching a baseball ball at a desired angle and speed, The object of the present invention is to provide an automatic launch device for a baseball ball that can be trained so as to be close to actual practice by allowing all of the left-hand pitching, and can be pulled and moved like a carrier by a compact volume.
